ACETY'LEN E-GAS G ENERATOR.

SPECIFICATION forming part of Letters Patent No. 693,248, dated February 1 1, 1902. p Application led January 2, 1901. Serial No. 41,8110. (No model-3 T0 a/ZZ whom it may concern,.-

Be it known that I, ALFRED C. EINSTEIN, a citizen of the United States, residingin the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Aeetylene-Gas Generators, of which the following is a full, clear, and eXact description, reference being had to the accompanying drawings,forming part of this specification.

Myinvention relates to a generator for the production of acetylene gas, and has particular reference to a feed-valveconstruction whereby the carbid is automatically deposited in the water, by which it is decomposed, according to the requirements of the generator.

My invention consistsin features of novelty hereinafter fully` described, and pointed out in the claim. t

Figure I is a vertical sectional view taken through my improved generator and the gasometer associated therewith. Fig. II is an enlarged detail view of a modification of the carbid-delivering valve. Fig. III is a longitudinal sectional View of another modification of the valve. Fig. IV is an enlarged ycross sectional view taken on line IV IV,

Fig. I'.

1 designates the tank ofthe generator, suitably supported and containing a water` and gas chamber 2. t

3 designates a carbid-receptacle mounted in the upper end of the` tank'l and closed by a cap 4 of the tank. The receptacle 3 is preferably of .hopper shape, as shown, in order that the carbid placed therein may fall'by gravity to a central position at the bottom of the receptacle. Access .to the interior of the receptacle 3 is provided for yby a hand-hole 5, closed by a cover 6. The cap Lis provided with a stutting-box 7 ,containin g suitable packing retained by a gland 8. Depending from the carbid-receptacle 3- is a stuffing-box 9, containing a compressiblefpackinglO, that is confined bythe cap 11.

12 designates the feed-valve, that operates through the stung-boxes 7 and 9 and through the carbid-receptacle 3. The valve 12 is of such length that it may be projected downwardly into the chamber 2 within the tank 1 and also extends exterior of the upper end of the tank for manipulation, as will hereinafterappear. Extendingthrough thefeed-valve 12' are aseries `ofducts 13, that lead in downward diagonal directions therein, said duets being. designedto communicate. with the interior of the carbid-receptacle 3 and also def` signed to communicate with the chamber 2.

to deliver carbid thereinto from the recepta 6o cle on the movement of the feed-valve.

The feed-valve may be of different forms this latter construction affording a minimum of weight.

In the practical use ofthe apparatus the feed-valve is operated to deliver the carbid from the `receptacle 3 into the chamber 2 by a suitable construction, suchas will nowbe y described.

14. designates a gasometer-tank into which the gas-pipe 15 leads from the chamber 2 of the generator-tank, and 16 is the gasometerl bell.4 The bell 16 carries an arm 17, equipped v y Y the upper end of the feed-valve 12.

19 is a counterbalance-weight carried by al with a foot 18, that is adapted to bear against rocking lever 20,"that `is, pivoted to a stand ard 21 and bears against a roller 22, mounted in. the lfeed-valve. i

'During the operation ofthe apparatus in the generation of gas the combined vweight of the valve 12, the bell 16, and parts carriedv thereby causes the valve to be moved downwardly whenever the gas in the gasometer is insufficient to hold the bell 16 elevated.' In such downward movement of the valve a charge of carbid equal to the holding capaeity of the ducts 13 is carried in said valve .downwardly therewith and discharged into the chamber 2, where it falls into the water therein to be decomposed and cause the generation of acetylene gas. As each duet 13 of the series in the valve 12 passes through the carbid-receptacle it receives a charge of carbid. If the amount of carbid delivered from the first duct 13, that discharges into the Water in the chamber 2, is insuicient to cause the generation of the requisite amount of gas, the valve continues to descend, oWin g to lack of support by gas previously generated and conveyed to the gasoineter, and additional carbid is delivered from the upper ducts 13 until the requisite amount of gas has been generated, according to the capacity of the apparatus. As soon as the gas-pressure is sufficient in the gasometer to raise the bell 16 the valve l2 is elevated by the counterbalance-Weight 19 and is upheld in position to receive a fresh supply ot' carbid until such time as the supply of gas becomes diminished, when the feeding operation of the carbid is again resumed in the same manner as before.

23 designates a drain-pipe applied to the lower end of the tank 1 and provided with a valve 24, through which the chamber 2 may be flushed.

I claim as my invention- In an acetylene-gas generator, the combination of a tank provided with a Water-chamber, a carbid-receptacle, a verticallyslidable valve or carrier arranged to slide through said carbid-receptacle, and provided with a series oi apertures extending diagonally and downwardly therethrough, and means for moving said valve up and down to convey the carbid deposited in said apertures :from said receptacle to said Water-chamber, substantially as described.
